Jim Kellerman commented on HADOOP-1574:
---------------------------------------

Do you think it will need to be changed again if HADOOP-1589 is committed?

> If multiple threads all try to create a table of a particular, all succeed.  It makes
for a mess. 
> Create table needs to be synchronized so only one thread creates a table and subsequent
threads fail with 'table already exits'.  The test for pre-existence also needs fixing.
